Hi Joel,
Very interesting and spectacular architecture historical premiére. The title is superb, the diagonal composition is excellent likewise. Beautiful photo with much information. Congratulations. Have a nice day!

Hello Joël,
I always like these sort of pictures. Roofs make fascinating subject and here they are nicely complemented by the old stone walls. Very good light with excellent natural colours. Fine photo work.

The first thing that struck me, even from the thumbnail, was how well the composition works with a strong diagonal from the top right. Looking at the proportions of the image I guess you cropped in order to emphasise that feature. All 3 images are good and you have been able to find some fantastic PsOV, especially "other sight" where it looks as if you were high in the air. :D.
